SNOW-MELTING APPARATUS.

SPECIFICATION forming part of Letters Iatent No. 281,500, datedJuly 17,1883,

Application filed February 5, 1883. (No model.)

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in whichsimilar letters of reference indicatecorresponding parts in all the figures.

Figure l is a plan view of my improvement,

parts being broken away. Fig. 2 is a sectional side elevation of thesame, taken through the line :0 m, Fig. 1. Fig. 3 is a sectional endelevation of the same, taken through the line y 3 Fig. 2.

The object of this invention is to facilitate the removal of snow fromstreets and other places.

A are the forward wheels of the carriage, the axle B of which isconnected with a high bolster, C. To the bolster C is attached theforward part of the frame D-, to which is attaohed the drivers seat E.The rear part of the frame D is attached to the rear axle, F, at theinner ends of the hubs of the rear wheels, G. The axle F is made incrank form, to bring its middle part near the ground. a

H represents a tank, which I prefer to make of oval form, but which maybe made cylindrical or of other suitable shape. To the sides of the tankH, a little above the level of its central line, are attached flanges I,which rest upon the side bars of the frame D, and support the tank H andits contents. The upper side of the tank H, except at the forward end,is open, so that snow can be readily shoveled in to the said tank. Theforward part of the tank H is covered by a plate, J, to prevent waterfrom splashing out upon the driver, and to cover and protect theinlet-openings of the overflow chamber and pipes.

Within the tank H is placed a'cylindrical furnace, K, which is made ofsuch a size as to leave a narrow waterchamber between its lower part andthe lower part of the tank H, and a larger space at the upper part ofthe said tank. The door of the furnace is at the rear end of thevehicle. The lower part of the forward end of the furnace K is closed,and its upper part is open, to allow the products of combustion to passfreely into the chamber L,

'of the furnace K. The chamber L rises a little above the top of thefurnace K, and with its upper part are connected the ends of a number ofexterior flues, M, through which the products of combustion pass to thechamber N, secured to the top of the rear end of the furnace K. With thetop of the chamber N is connected the smoke-stack 0.

To the forward end' of the furnace K and the forward side of thesmoke-chamber L is connected a water-chamber, P, which has openings Q inits top, and with the inner side of which, a little distance below thebottom of the chamber L, are connected two pipes, R. The pipes R extendwith a downward inclination through the side parts of the furnace K, andare connected at their lower ends with a pipe, S, which crosses thefurnace K'near its door. The ends of the cross-pipe S project throughthe lower parts of the sides of the tank for the convenient discharge ofthe water. The projecting ends of the pipe S may be left open, ormay beprovided with nozzles or hose,

so that the discharged water can be directed to any desired place.

vWith the end parts of the cross-pipe S, between the walls of thefurnace K and tank H, are connected the lower ends of inclined pipes T,the upper ends of which are a little above the water-line of the tank H,so as to discharge the steam generated in the pipe S into the snow uponthe fines M and assist in melting the said'snow.

In using the apparatus the snow is shoveled into the open top of thetank H, and is melted by the heated walls of the furnace K and flues M.As the water rises to the top of the chamber I it flows through theopenings Q into the chamber P and pipes R S, and is heated, so that whendischarged from the pipe S it will melt any snow left upon the ground orin the gutters as it flows into the sewer.

To the walls of the tank H, above the fines M, is attached a grate, U,of wire or other suitable material, to prevent any coarse rubbish thatmay be thrown into the tank with the snowfrom passing down into thespace between the walls of the furnace K and the tank H. The end of thetank H below the furnace K is provided with a short pipe, V, closed by acap or a stop-cock, through which fine dirt IOO that may pass throughthe grate U can be washed out.

If desired, the chamber P can be omitted and the pipes R extendedforward and curved upward to bring their ends to the level of thewater-line of the tank H, to carry off the overflow-water, the saidpipes thus forming the overflow-chamber P.

I am aware that it is not new in a snow-melting machine to combine afurnace lined with water-jackets filled by melting snow and ice, areceiver having an inclined bottom and dis charge-nozzles, and an enginedriven by the steam generated by the heat of the fire which heats thereceiver.

hat I claim as new and of my invention is 1. In a snow-meltingapparatus, the com bination, with the tank H, of the interior fur nacc,K, provided with the chamber L, and a series of exterior return-fines,M, substantially as herein shown and described, whereby the snow will bemelted as it is thrown into the said tank, as set forth.

2. In a snmwmelting apparatus, the combination, with thetank H and theinterior furnace, K', of the overflow-chamber P and the pipes R S,passing through the said furnace K, substantially as herein shown anddescribed, whereby the overflow-water will be heated and made to meltand wash away any snow that may be left upon the ground, as set forth.

3. In a snow-melting apparatus, the combination, with the tank H, theinterior furnace, K, and the overflow-pipes R S, of the steanrpipes '1,substantially as herein shown and described, whereby the steam generatedin the said overflow-pipes can be made to assist in melting the snow, asset forth.

4. In a snow-melting apparatus, the combination, with the tank H, thefurnace K, and the return-fines M, of the grate U, substantially asherein shown and described, whereby MICHAEL HANNAN.
